A playable brief can have a full asset folder and still leave the central interaction undecided. For a founder preparing a production request, the useful distinction is between the materials available and the decisions already made.

Calling the job build only is clearer when the route through the experience has been chosen. Otherwise, concept work remains inside the request even if no one has named it.

Walk through the player's route

Start with the opening frame. Show what the player is expected to do, how the screen responds and how the experience reaches its end card. The detail can be proportionate to the job; the point is to make the intended route visible.

For example, choosing between tapping an object and dragging it into a target is not merely a wording change. It can affect the layout, gesture handling and feedback the build needs. Resolve that choice or mark it as an open decision.

Put materials and delivery beside the route

Identify which assets are ready for production, which need preparation and which are still missing. Record the intended network and export requirements so the implementation is not designed around an assumed destination.

You do not need to invent a specification you cannot confirm. Name the person responsible for checking it and show the open item in the brief.

Give the missing work an owner

When the route is open, define the concept decision that must be made next. Who chooses the interaction? Who approves the visual direction? What material is needed to make that decision?

When the route is already agreed, production can estimate and build against it. Any later request to change that route can then be discussed as a visible scope change rather than an argument about what everyone supposedly understood.

Use the check without turning it into bureaucracy

For a small unit, a few annotated frames may answer these questions. The goal is not a long document. It is a brief that lets both sides point to the same first move and know what remains unresolved.

Mark the first undecided move in your next playable brief and assign the decision before requesting a build only estimate.
